FRONT LAMP UNIT MOISTURE CLEARING
Some moisture accumulation inside a vented front lamp unit is normal. This normal moisture will appear as a fogging on the inside of the lamp lens, similar to the fog that sometimes appears on the inside of a windshield. This moisture may be removed by activating the headlamps on HIGH beam for 15 minutes.
If water droplets larger than 1.5 millimeter (0.059 inch) in size have accumulated on the inside of the lamp lens, the front lamp unit should be replaced.
